Stabilize is Bluring Footage
I was doing some compositing work on a shot with a moving camera. In order to make my painting, etc, easier I stabilized the shot, then precomped it. Then in my final comp, I unstablized it by applying the inverse keyframes. This worked great, however, the footage is visibly blurred. I’m not sure why this occurred. There is no scaling happening, only position keyframes. I tried continuous rasterize, and that doesn’t solve it. There is no motion blur on so therefore position keyframes, even if they happen 1 per frame should not blur footage. Is there something that I’m missing here. Please help.

Do you happen to have a camera on the scene?
If so maybe DOF is on. It´s just a guess. I don´t really know enough to say but it occourred to me.
Sorry if it does not help.
Good luck.

No cameras in my shot.

Dave,
I originally had that thought too, but because they are using the clone stamp, using paint on transparent does not work. It basically produces a blank frame.

So I’ve been doing some research and experimenting and discovered that turning the layer to draft quality makes the blur stop. I know this has to do with subpixel repositioning, but it seems that it could easily screw up the look of other effects and layers if I leave the final render at draft quality. Any ideas?

Add this expression to anchorPoint and Position:
[ Math.round(value[0]) , Math.floor(value[1]) ];
should your footage and comp have an odd number as width and height, you’ll need to add [0.5 , 0.5] to that.

Hi How did you invert your transform. try pickwipping anchor point to position and position to anchor point between the comp with the stabilization and the comp where you revert the stabilization. Make sure that in the comp in which you revert the stabilization that collapse transformations is turned on.
